INT 15 - DESQview v2.20+ - "ASSERTMAP" - GET/SET MAPPING CONTEXT
AX = 1117h
BX = 0000h      get current mapping context without setting
nonzero    set new mapping context
Return: BX = mapping context in effect before call
interrupts enabled
Notes:  this function differs from AX = DE17h for DESQview v2.20 through 2.25
mapping contexts determine conventional-memory addressability; setting
a mapping context ensures that the associated program and data areas
are in memory for access.  Usable by drivers, TSRs and shared
programs.
caller need not be running under DESQview, but must ensure that the
stack in use will not be mapped out by the call
